Let's say you initially create a cursor and set it as the recordsource
of the grid. Once you run a query to repopulate the new cursor you
have temporarily lost control of the cursor and it can bring back
any type of structure. By setting it to "" between queries VFP takes
no action and then when the cursor is reset with the same structure all
is well. At least that sounds good to me and is close to what is happening.

>>>Working in VFP 5.0 - I have a form with a grid hardcoded on it. The table the grid is populated by is a temporary table, not part of the database. The grid loads up just fine. I have a button that the user clicks on to update some fields and need the grid to refresh. I have not been able to get this to work. Whenever I try to refresh I just get a blank grid screen or an error telling me that it doesn't recognize the columns of the grid (Unrecognized Member). Can anyone help me out? Why can't I refresh the grid?

>>>TIA!
